WATER-FILTER.

SPECIFICATION formingpart of Letters Patent No. 555,685, dated March 3,1896. A Application filed May 25,1895. Serial No. 550,633. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK W. EDGING TON, a citizen of Great Britain,residing at ter, and which also shall be so constructed as to facilitatethe removal of said sediment.

The invention consists in certain features of improved construction andin the novel combination and arrangement of parts, and first will bedescribed with reference to the accompanying drawings, after which thecharacteristic features thereof will be particularly pointed out anddistinctly defined in the claim at the close of this specification.

Figure 1 of the drawings shows in vertical section a water-filterembodying my invention in the best form thereof whichl have yet devised.Fig. 2 is a plan of one of the perforated disks which I employ asbackings for the wire-gauze disks. Fig. 3 is a view of one of thewire-gauze disks.

At 1 is shown the casing or shell of the filter. This preferably iscylindrical in its general form, and has at the upper end thereof, asshown in Fig. 1, a head 2 which is integral therewith. At 3 is the lowerhead, it being provided with a screw-threaded flange 31, which fitswithin the correspondingly screwthreaded lower end of the casing orshell 1.

, At 4 is a tube, formed with the body or shell 1, and communicatingthrough its passage with the interior of the body or shell slightlybelow mid-length of the latter. This tube is screw-threaded exteriorlyfor the application of a union or coupling by means of which to connectit with the pipe through which the water comes. At 5 is a similar tube,formed integral with the fixed head 2, and communieating through itspassage with the interior of the body or shell at the upper end thereof,the said tube 5 being screw-threaded exteriorly to facilitate theapplication of a union or coupling by means of which to connect with itthe pipe which leads to the point at which the Water is used. The filterherein shown and described is designed especially for application to thepipes which supply a dwelling-house with water, and preferably will beapplied at the point where the pipes connecting with the main enter thehouse and join the pipe within the latter. The tube 4 constitutes theinlet for the filter and is to be joined with the service-pipe leadingfrom the main. The tube 5 constitutes the outlet for the filter, and isto be joined with the pipe which leads the water to the desired pointsin the house. The removable head 3,

likewise, is provided with a tube 6, similarly screw-threadedexteriorly,for connection with a drain-pipe. lnteriorly the body orshell is provided with three flanges 7 8, and 9, which are formedintegral with the inner surface of the said body or shell. The lowest ofthese rims or flanges, which is designated by the numeral 7, is belowthe point at which the tube 4 communicates with the interior of the bodyor shell. The rim or flange 8 is located above the said tube 4, and therim or flange 9 is located near the upper end of the body or shell 1 ata slight distance below the head 2. The lowest rim or flange, 7, isnotched vertically, as at 10, and the top rim or flange, 9, is somewhatwider than the other two-that is to say, it projects farther toward thecenter of the body or shell than the said other two.

To the under side of each of the rims or flanges 8 and 9 is applied aperforated metal disk 11, one of which is shown separately in Fig. 2,and beneath each of the said disks 11 is applied a disk of wire-cloth12, one of which is shown separately in Fig. 3. The perforated disk 11and wire-cloth disk 12 are secured to their rim or flange 8 or 9 byscrews 13, which pass through holes 14:, formed in the said disksadjacent to the edges thereof, the heads of the screws being below thedisks, while their threaded stems enter threaded holes that are providedtherefor in the rims or flanges. The reason for making the top rim orflange 9 wider than the lower two is to enable the disks 11 and 12,which are applied to the said top rim or flange, to be made sufficientlysmall in diameter to be passed upwardly by the two lower rims orflanges, 7 and S, and yet extend completely across the opening withinthe said rim or flange 9. The lower disks, 11 and 12, are of a size tofit against the lower surrace of the rim or flange S, and in order toprovide for the passage of the said disks by the lowest rim or flange,7, I provide in the latter the notch or notches 10 already referred to.The space 23 between the two sets of disks 11 and 12 is filled withsuitable filtering material (indicated at 15) and constitutes afiltering-chamber.

To the under side of the lowest rim or flange, 7, I attach by screws 13a diaphragm 16, having a central hole or passage 17 therethrough, thesaid diaphragm 16 preferably being dished or concaved somewhat, asindicated in Fig. 1, and being arranged with the concavity uppermost.The space 18 above the upper disks, 11 and 12- that is to say, betweenthe said disks and the fixed head 2constitutes an aceumulating-chamberto provide for containing a supply of water sufficient to insure acontinuous flow out through the outlet 5. The space 19 below thediaphragm 16 is a sediment-chamber, into which sediment deposited by thewater which enters the central space 20 between the diaphragm 16 and thelower disks, 11 and 12, passes through the central opening 17 in thediaphragm 16. The downwardly-sloping upper sides of the diaphragmfacilitate the passage of the said sediment to and through the opening17. The inner surface of the fixed head 2 is rounded and its wallsgradually converge to the outlet 5 to facilitate the movement of thewater from the accumulating-chamber 18 through the said outlet. Thediaphragm 16 prevents disturbance of the contents of the sedimentchamber19 by the water flowing in through the inlet 4. I have indicated indotted lines in Fig. 1 a pipe 21, screwed onto the exterior of the tube6 of the lower head, 3, and provided with a stop-cock, the handle ofwhich latter is intended to be represented at 22. When it is desired toclear or flush out the sediment from the filter, this handle 22 may bemoved to open the stop-cock, whereupon the flow of water downwardlythrough the opening 17,in the diaphragm 16,into the chamber 19, andthrough the outlet 6 will effectually remove such sediment as may becontained in the chamber. Normally the stopcock is intended to beclosed.

What I claim is The water-filter consisting of the body or shell 1, thefixed head 2, the removable head 3, the inlet 4 in the side of the bodyor shell, and the outlets 5 and 6 in the respective heads, the rims orflanges 7, 8 and 9, on the interior of the said body or shell, thebottom one of said rims or flanges being notched as at 10 and the topone being wider than the other two, the perforated disks 11 andwirecloth disks 12 secured to the two upper rims or flanges and havingthe filtering-chamber between them, the diaphragm 16 with its openingsecured to the bottom rim or flange, the sedimentchamber below the saiddiaphragm, and the accumulating chamber above the top pair of disks, allsubstantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
